LESLIE: John in New Jersey, welcome to The Money Pit. How can we help you today?JOHN: Yes, thank you for taking my question. I have a stone patio that I constantly have weed problems with and I’ve used a spray. Somebody said that you can use [brushed cement] (ph) or something. What would you suggest to get rid of those weeds?TOM: I would use Roundup.JOHN: Yeah, I’ve done that but they keep on coming back. Is there any permanent solution?LESLIE: Are they growing in between the stones themselves; sort of in like the grout line?JOHN: Between the stones themselves, yes.TOM: Yeah.LESLIE: There’s a product called JOINT-LOCK locking sand. Is it from QUIKRETE, Tom?TOM: It’s QUIKRETE that makes it, yes.LESLIE: And it’s sort of like a polymer sand product.TOM: It’s a polymer-based sand. It’s sort of like sand with a glue in it.LESLIE: Yeah, that you would sweep over the stone patio surface so now you’re filling in the essential grout lines with this sand. And then once it’s filled in, you would spray it with a hose and that sort of glues all of that sand together, making it impossible for bugs and weeds to grow up in between. But it’s not a permanent bond. Say you should ever need to replace one of those stones for whatever reason, you can sort of jiggle it loose and then pop a new one in.JOHN: I see. That’s perfect. Thank you very much.TOM: Alright, well good luck with that project, John. Thanks so much for calling us at 1-888-MONEY-PIT.
